Top specs

  • Type

    NVR

    Recorder that uses IP cameras and network connection for video recording and management.

  • Number of Channels

    The maximum number of cameras that can be connected to and managed by the recorder

  • Resolution

    4K

    The highest resolution available on the market (also known as 8 Megapixels). It offers 4 times more detail than Full HD. This is cinematic quality that allows for maximum possible zoom to recognize critical details, even from a great distance.

  • Incoming Bandwidth

    This is the actual processing power of the recorder. It determines how much "load" (data) it can handle simultaneously from all cameras. A high number is necessary for many channels at high 4K resolution.


    • Example 1: You have 4 cameras of 5MP (each requiring ~8 Mbps). A total of ~32 Mbps is required. An NVR with 80 Mbps Incoming Bandwidth is more than enough.
    • Example 2: You have 16 cameras of 4K (each requiring ~12 Mbps). A total of ~192 Mbps is required. An NVR with 160 Mbps is not enough and will "lose" cameras or reduce their quality. Here, you need an NVR with at least 256 Mbps.

    100

  • HDD Slots

    The number of internal hard drives (SATA) that can be installed simultaneously in the recorder.

  • Maximum Capacity per Disk

    The maximum size (in TB - Terabytes) of the hard drive that the device "recognizes" and supports in each slot.

  • Ports

    HDMI

    The digital output for video and audio. It is the standard way to connect the recorder to a modern TV or monitor (PC) and view your cameras in high resolution.

    USB

    Its main use is to connect a mouse for menu navigation and settings. Additionally, it is used to connect a USB stick (flash drive) in order to export (take a backup of) specific video clips that interest you.

  • Video Compression

    H.265

    Advanced codec with approximately 50% better compression than H.264 for the same quality. Ideal for 4K and 8K content, supports HDR and UHD, significantly reducing the required bandwidth.

    • The standard supports approximately 30–35 days of continuous recording on a 2TB hard drive

    (The values and durations are indicative and based on standard settings. Actual performance may vary depending on resolution, frame rate, scene motion, and hardware.)

Description

At a glance

  • 4K Ultra HD: Top image resolution for detecting every detail.
  • High Storage: Supports hard drives up to 16TB for long-term archiving.
  • BLE Setup: Fast and simple configuration via Bluetooth.
  • H.265 Compression: Reduces data volume without loss of image quality.

Crystal-clear Surveillance

You will find that the 3840 x 2160 resolution offers a new dimension in security. The Ajax NVR manages 8 channels with 100 Mbps bandwidth, ensuring that every movement is recorded with absolute smoothness and clarity, even in demanding scenes with intense activity.

Smart Storage

You will appreciate the flexibility provided by the support for SATA drives up to 16TB. The use of the H.265 codec allows for optimal space management, giving you the ability to keep a history of many days in high resolution without worrying about the system's capacity.

Modern Connectivity

You will find the BLE function extremely useful during installation. It allows the recorder to communicate directly with your device for quick setup, while the Ethernet port ensures stable data transfer to your network, keeping the system always online and reliable.
